Dahlek is right about tonic water, my husband was drinking it for the charley horses he get with his rhuematoid. He hated it though so recently I ordered Country Life calcium/magnesium 1000mg-500mg and that is doing the trick for him. Also very helpful for me and the narcotic constipation with my norco. I got it from Iherb rather quickly with my B-12 restock.
By the way I would love to give your principal the "what for", Karma......I truly believe what goes around comes around.
